I've tracked sleep using a number of devices and algorithms and I haven't found a single one that regularly aligns with what and how I feel.

I know it's tracking real data, but the conclusions feel completely made up.

What are other people's experience -- especially from those who are more bullish about sleep tracking?

guzik•31m ago
by tracking sleep, what exactly do you mean by that? sleep phases, sleep score, sleep duration?
dmvaldman•22m ago
it's a lot of work, but something you could do is track how you feel (manually or some other way) and do a similar statistical analysis. chess elo was just convenient and aligned for me.

I hope Garmin sees your passion project and greenlights it for inclusion. You have the right approach to ensuring folks are at their optimal health to grow intellectually as a person.

thank you! i think it's ridiculous how little they invest in their developer ecosystem. i have been thinking about jumping ship to oura or whoop simply because of this.
